    Subject[PATCH 5.10 016/152] dt-bindings: display: sii902x: Add supply bindings
    Date
    From: Alexandru Gagniuc <mr.nuke.me@gmail.com>

    commit 4c1e054322da99cbfd293a5fddf283f2fdb3e2d0 upstream.

    The sii902x chip family requires IO and core voltages to reach the
    correct voltage before chip initialization. Add binding for describing
    the two supplies.
